       2. Apparatus according to claim 1 wherein a stop is arranged on the cover for determining the closure position and which forms a handle supported against the edge of the container in the closure position. 
     
     
       3. Apparatus for supplying cooling and/or polishing liquid to a processing station, such as for use in machines for grinding and/or polishing optical lenses, comprising a supporting frame adapted to be located at the side of a machine with which it is to be used,   a storage container removably insertable in the frame,   a cover for the container having side edge regions and a downwardly depending outer perimetric edge, and supporting thereon a discharge pipe for the liquid and a device for conveying the liquid from the container through the pipe for conducting the liquid to a processing station,   hinge joints pivotally mounting the cover on the frame,   the container having inside perimetric dimensions and the outer edge of the cover having corresponding outer perimetric dimensions and the outer perimetric dimensions of the edge of the cover being smaller than the inside perimetric dimensions of the container, and   stops arranged at the side edge regions of the cover for limiting the pivotal angle of movement of the cover between a closure position in relation to the container and a correspondingly opposite open position, and   wherein a pipeline is provided which is adapted for discharging liquid from the region of the processing station into the container, and which has a pipeline portion arranged on the cover and passing through at least one of the hinge joints, a pipeline portion arranged on the frame, and a rotary coupling interconnecting the pipeline portions.   
     
     
       4. Apparatus according to claim 3 wherein the pipeline portion passing through said at leastone of the hinge joints forms the corresponding hinge joint axle therefor. 
     
     
       5. Apparatus according to claim 1 wherein the cover is cup-shaped. 
     
     
       6. Apparatus comprising a storage container for supplying liquid and having an upper inside peripheral edge portion defining an upper opening of selective dimension therein,   a conforming cover for covering the container opening and having a depending outside peripheral edge portion of sufficiently smaller corresponding dimension than that of the container opening to provide a clearance gap therebetween, and supporting thereon means for conveying liquid from the container which extend downwardly from the cover into the container when the cover is in covering relation thereat, and   mounting means including stationarily arranged and pivotally coacting pivot means thereon arranged for stationarily pivotally mounting the cover on the mounting means for pivotal movement of the cover along a fixed path about a stationary pivotal axis stationarily arranged on the mounting means between a closure position in covering relation across the container opening inwardly of the clearance gap and in spaced relation to the container and an open position remote from the container opening, said container being arranged relative to the cover to provide open communication between the container interior and the container exterior through such clearance gap when the cover is in the closure position.   
     
     
       7. Apparatus according to claim 6 wherein stop means are provided for limiting the range of movement of the cover between the closure and open positions. 
     
     
       8. Apparatus according to claim 6 wherein the cover has a cover stop extending peripherally outwardly therefrom sufficiently for spanning the clearance gap and for contact with the container edge portion for limiting the movement of the cover upon reaching the closure position. 
     
     
       9. Apparatus according to claim 8 wherein the cover stop includes a handle portion for manually opening the cover. 
     
     
       10. Apparatus according to claim 6 wherein the mounting means includes a support adjacent the container and having a support stop for contact with the cover for limiting the movement of the cover upon reaching the open position. 
     
     
       11. Apparatus according to claim 6 wherein the mounting means includes a support and hinge joint means pivotally interconnecting the cover and support. 
     
     
       12. Apparatus comprising a storage container for supplying liquid and having an upper inside peripheral edge portion defining an upper opening of selective dimension therein,   a conforming cover for covering the container opening and having a depending outside peripheral edge portion of sufficiently smaller corresponding dimension than that of the container opening to provide a clearance gap therebetween, and supporting thereon means for conveying liquid from the container which extend downwardly from the cover into the container when the cover is in covering relation thereat, and   mounting means arranged for mounting the cover for movement between a closure position in covering relation across the container opening inwardly of the clearance gap and an open position remote from the container opening, and   wherein the cover has a cover stop extending peripherally outwardly therefrom sufficiently for spanning the clearance gap and for contact with the container edge portion for limiting the movement of the cover upon reaching the closure position, the mounting means includes a support and hinge joint means pivotally interconnecting the cover and support, the hinge joint means includes a support hinge part connected to the support and a cover hinge part connected to the cover and having a radial projection, and the support has a support stop for contact with the radial projection for limiting the movement of the cover upon reaching the open position.   
     
     
       13. Apparatus according to claim 11 wherein the hinge joint means includes a hinge joint, and liquid pipeline means for the container are provided including a support pipeline part on the support, a cover pipeline part on the cover arranged for flow communication with the container through the container opening and having a pipeline portion thereof passing through the hinge joint, and a rotary coupling coaxial to the hinge joint and interconnecting the pipeline parts for relative rotational movement about the hinge joint. 
     
     
       14. Apparatus according to claim 13 wherein the pipeline portion passing through the hinge joint forms the axle for the hinge joint. 
     
     
       15. Apparatus according to claim 11 wherein the hinge joint means have a hinge axis positioned substantially coincident with a vertical plane passing through the upper inside peripheral edge portion of the container adjacent thereto to prevent spillage or dripping of liquid from the cover and from the means supported thereon beyond the vertical perimetric confines of the container opening in any position of movement of the cover relative to the container.
